Bronchitis is a very common disease in the department of respiratory medicine, with many and complex triggering factors. It can be divided into acute bronchitis and chronic bronchitis based on the duration of the disease. Typically, middle-aged and elderly people have a high likelihood of suffering from chronic bronchitis. For bronchitis, whether chronic or acute, the main clinical symptoms include cough, phlegm, shortness of breath, chest tightness, and even difficulty breathing. Therefore, for patients experiencing these clinical symptoms induced by bronchitis, it is generally not advisable for them to smoke or drink alcohol. Alcohol is considered a spicy and irritating substance, and if a patient with bronchitis already exhibits repetitive symptoms of coughing and phlegm, drinking alcohol could potentially spread the inflammation and exacerbate the clinical symptoms. Hence, patients with bronchitis should not drink alcohol.
